Synthesis and Cross-Linking in the Structure and Growth of Hair Keratins

    October 1988 in “ Clinics in Dermatology ”
    George E. Rogers
    TLDR The molecular details of hair growth are not well understood.
    The document discussed the biochemical mechanisms involved in hair growth, highlighting the limited understanding of molecular events within the hair follicle at the time. It described the process of hair cell migration from the bulb region, taking approximately 5 days to become keratinized. During keratin synthesis, the -SH content in proteins decreased rapidly due to oxidation to disulfide bonds, reaching an oxidized state within 6-12 hours. Despite extensive literature, the hair follicle remained a "black box" in terms of detailed molecular knowledge.

      A 20-year-old shared their experience of reversing hair loss without using minoxidil or finasteride, instead relying on supplements like biotin, collagen, fish oil, saw palmetto, and various vitamins. They emphasized the importance of a balanced supplement schedule and noted improvements in hair health without experiencing additional shedding.

      community Keratin microspheres - breakthrough

      in Research/Science  13 upvotes 1 year ago
      A gel of keratin microspheres promotes hair follicle growth, showing similar effectiveness to minoxidil in mice. The treatment activates hair growth pathways and reduces inflammation, with potential applications in drug delivery for hair-related disorders.
